NBC is moving its low rated Thursday dramas Aquarius and Hannibal to Saturdays. Dateline Mystery will take over the ti 9-11PM timeslot. According to Variety, the timeslot change will begin this week. Hannibal has already been canceled, while NBC recently ordered a second season of Aquarius. Last week’s episode of Aquarius earned a 0.5 adults 18-49 rating, while Hannibal scored an 0.4. The timeslot downgrade to the Saturday night dead zone could be a sign that NBC is reconsidering its decision to renew Aquarius.
